C. Hamilton Bloomer was the editor up until the Vol 2 No. 5 issue of May 1937. By Vol 3 No. 1, released in October 1937, Bloomer was busy with NAPA {National Amateur Press Association) for which he went on to produce at least four issues of his amateur magazine The Bloodstone. He appointed Roy Squires as his successor at SFAA, and Tesseract was then edited by Raymond Van Houten and was retitled New Tesseract. The last issue was published in March 1938.

Featured in Tesseract were articles such as "Story Writing Hints" by Clark Ashton Smith, "Degeneration: A Note on Stanton A. Coblentz" by Peter Duncan (Stanton Coblentz was a writer and publisher of Wings), and poetry such as Atlantis by Clark Ashton Smith.

Tesseract is also notable for the publication by a 15-year-old James Blish of an article which he attributed to Nils Frome that Frome did not write, which resulted in some controversy and rebuttal in the pages of Frome's fanzine Supramundane Stories.
